如何在 RPM SPEC 文件中使用正则表达式？

BuildRequires: perl(Regexp::Common)

#!/usr/bin/perl
use strict;
use warnings;
use Regexp::Common qw /URI/;

my $text = "Visit http://www.example.com for more information.";
if ($text =~ /$RE{URI}{HTTP}/) {
    print "URL found: $&\n";
} else {
    print "No URL found.\n";
}

%build
%__perl -Mblib /path/to/regex_install.pl

%install
mkdir -p %{buildroot}/usr/local/bin
install -m 755 /path/to/regex_install.pl %{buildroot}/usr/local/bin/

%files
/usr/local/bin/regex_install.pl
